After River had explained the situation once more to the DocTwo and Rose, the DocTwoimmediately set about to talking a mile a minute, informing River that this universe's Torchwood tower was also set on a rift, just as the one back home had been. She didn't comment on the fact he still referred to her universe as home, just nodded when he informed her he believed they could get a message through if they found a larger rift and projected a signal of some sort and aimed it at Jack's hub.

River nodded, her work on Area 52 coming to mind, and she smiled in remembrance.

"So, Sweetie, how exactly do we find this larger rift?"

"Well, Professor, first I need to see your ship."

When the ship was brought back to the Tyler mansion, the DocTwo hopped around excitedly as he explored his first working (theoretically) space- time machine in months.

"..add this to the temporal accelerators and if I rewire a couple of those dimension hoppers Rose used to go back, we could jumpstart this ship into a working vessel! Then you would just need to create a signal that would reach a different dimension and Bob's your uncle!"

"How long would that take?" asked Rose, caught up in his excitement.

"Well, it'll probably take about three days for the jumpers to recharge after I rewire them. Then it's just a matter of how long it takes River to build the signal."

She turned to Rose, "I've built something similar before for an entirely different reason, but it's the same principals. I just have to modify my original plans to be more mobile than that was."

"Right, then it should take no more than a day to locate the optimal rift."

"Then what? The Doctor can't just come through dimensions, he'd be stuck 'ere and the TARDIS will fade out like it did the last time."

"Oh, I wouldn't worry about the Doctor, dear. He can be very resourceful. Just tell him where he needs to be, and let him worry about how to get back."

"I know that, I've known the Doctor longer than you, you know. 'ow long did you say you've been traveling with him now- five whole months?"

River laughed teasingly at that- "Oh, my dear, the Doctor and I've known each other for a very long time, I can assure you. And very, very well." Her voice dropped suggestively at this last add- on.

The DocTwo cleared his throat and looked intently on his work while Rose crossed her arms and stared at him. He tried changing the subject.

"What we should really be trying to figure out is how you got here. Even with vortex jumping he'd been doing, that's not nearly powerful enough to transfer you to a different dimension. So what happened that drew you here?"

"That's what I'd like to know," replied Rose grumpily.

"No idea, Sweetie. All I know is I'm here now, so may as well make the best of it."

Making the best of it, apparently, meant River Song moving in to the Tyler house.
